The inquiry was registered on the basis of "evidence" the CBI collected against Mr Jain, saying he was involved in money laundering as public servant through Kolkata-based Prayas Info Pvt Ltd, Akichand Developers, Indo Metal Impex Pvt. Ltd, and Mangalyatan Project Pvt Ltd.

Income Tax Department investigations in 2013 had allegedly found that Rs 16.38 crore was received by these four shell companies.
